individuals whose characteristics are similar to those of your program participants; these individuals do not receive any services, or receive a different set of services than those you are evaluating.
A group of individuals whose characteristics are similar to those of a program's participants. These individuals may not receive any services, or they may receive a different set of services, activities, or products; in no instance do they receive the same services as those being evaluated. As part of the evaluation process, the experimental group (those receiving program services) and the comparison group are assessed to determine which types of services, activities, or products provided by the program produced the expected changes.
A group that is exposed to all the conditions of a study except for the variable being tested; in Scientific Learning outcomes studies, the variable being tested is the Fast ForWord product.
a large number of industries grouped together to represent the typical industry
The group of peer institutions used for comparison purposes within the IPEDS Peer Analysis System (PAS). Comparison groups may be identified by the analyst by name or UnitID, they may be built by using characteristics (variables) from the IPEDS data, or they may be automatically generated by the system. Also referred to as a peer group. Automatic peer group LinchPin (institution)
A group of study participants who do not receive a treatment or intervention that is compared against a group that is receiving the intervention. The use of a comparison group implies that the study is not a randomized controlled study (see controlled study and randomized study).
Any group to which the index group is compared. Usually synonymous with control group. ( Harm, Therapy)
A control group randomly selected and matched to the target population according to characteristics identified in the study to permit a comparison of changes between those who receive the intervention and those who do not.
in a quasi-experimental research design, this is the group of research subjects that, for the sake of comparison, does not receive the treatment or intervention given to the intervention group. Comparison group subjects are typically not randomly assigned to their condition, as would be true of control group subjects in an experimental design study. See: control group, experimental group.
A group that provides a basis for contrast with an experimental group (i.e., the group of people participating in the program or project being evaluated). The comparison group is not subjected to the treatment (independent variable), thus creating a means for comparison with the experimental group that does receive the treatment.
Participants in a comparison group do not receive the interventions of a project being tested. The comparison group is studied to provide more conclusive evidence that changes observed in the project participants are due to the project.
A group that provides a basis for contrast with the study group – that is, the group participating in the activity or program being evaluated Comparison groups are generally selected to be as similar as possible to the study group by matching the distribution of characteristics that are believed to be important in affecting the study group's response to the activity or program being evaluated Related term: control group EHR/NSF Evaluation Handbook, Chapter Seven: GlossarySource web site
